USPTO Group and Art Unit Predictor

After filing your patent application, the USPTO will assign it to a group and art unit for examination. Different groups and art units (and the examiners within them) can have very different grant rates.

Use our predictor tool to steer your patent application to a desired group and art unit. If you don't like our prediction results, edit your claims and try again.
